Nuclear power plant is described as a power plant in which nuclear energy is converted into heat for use in producing steam. The main challenge faced globally is gathering enough energy foráthe increasing populationáand controlling the carbon emission caused by the usage of fossil fuels. To overcome this, nuclear energy can be used as an alternative power source. This book includes research work and technical experience from differentápower plantsáand research institutions around the world.áIt discusses various topics like nuclear systems protection, design and modeling of critical parameters in nuclear power plants, thermal-hydraulic analysis, nuclear waste management and safety assessment. The book consists of significant information which will be of interest to scientists and those in technical areas ofánuclear power plants.
